JAMES REAGAN AND WILLIAM REAGAN, OF PHILADELPHIA, PENNSYLVANIA; SAIDWILLIAM -,REAGAN ASSIGNOR TO SAID JAMES REAGAN GRATE Specification ofLetters Patent.

Patented June 22, 1909.

Application filed September 4, 1908. Serial No. 451,641.

To all whom it may concern:

Be it known that we, JAMES REAGAN and WILLIAM BEAGAN, citizensof theUnited States, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Grate, of which thefollowing is a specification. Our invention relates to a new and usefulshaking grate and consists in providing a reversible lifting fire barwhich can be used with or without choppers.

It further consists of. novel means for mounting the same whereby alifting fire bar can be removed independently of the others.

It further consists of other novel details of construction, all as willbe hereinafter fully set forth. I

Figure 1 represents a side elevation of a reversible lifting fire barshowing the rocking bars upon which the same is mounted. Fig. 2represents a side elevation showing a reversible lifting fire barwiththe parts disconnected. Fig. 3 represents an end elevation thereofshowing a chopper on opposite sides thereof, in dotted lines. Fig. 4repplan view of a reversible lifting fire bar. Figs. 5 and 6 representsaid elevations, on a smaller scale, showing the bar in its differentpositions.

Similar numerals of reference indicate corresponding parts inthe-figures.

Referring to the drawings:-We have found-in shaking grates that it is ofadvantage toprovide a construction where there are no dead points in thefire and in which free passage of air is permitted and caused in orderthat a suitable draft is provided and we'have further found that in some1nstances it is of advantage tobe able to raise a fire bar in either onedirection or the other.

Our invention is designed to accomplish these results and in thedrawings we have shown a construction for carrying out the same, but itwillbe evident that various changes may be made which will come withinthe scope of our invention and we do not therefore desire to be limitedin every instance to the exact construction as herein sh ewn anddescribed but desire to make such changes a s'may be necessary. I

We desire it understood that our reversible fire bar is adapted for useon any suitable construction of grates and we desire to use the sameeither in conjunction with rocking choppers or not, as mayv benecessary.

In some instances we may alternate" the reversible lifting fire barswith choppers or we may make sections entirely-of, the reversiblelifting fire bars, the use and arrangement of the parts, depending uponthe conditions.

1 designates a hollow reversible lifting fire bar which is preferablyformed of the upper and lower sections 2 and 3 respectively, the uppersection in the present instance being provided with the top face lhaving the slots or perforations 5 therein and having on the facethereof at the opposite ends thereof, the laterally extending shoulders6 and 7 The section 2 is provided with the downwardly extending sides orwings 8,

which are provided with the slots or perforations 9 and the edges 10 and11 of said sides 8, converging toward each other. The section 3 of thelifting fire bar is formed with the front and rear faces 12 and 13 whichare provided with the slots of perforations 14 and the inner edges 15and 16 of the section 3- converging toward each other from the topdownwardly. Any suitable means for connectin the section may be employedand in the (rawings we have shown the openings 17 in the upper sectionadapted to receive the tongue 18 of the lower section.

19 designates cars or lugs projecting from the lower section, which isadapted to be pivotally connected with a bar 20, which is connected withsuitable actuating mechanism for operating the reversible lifting firebar.

21 designates rocking bars upon which we preferably mount the choppers22 on opposite sides of the reversible lifting fire bar 1 and upon thesaid rocking bar 21 we mount the sleeves 23 which have, projecting fromthe opposite ends thereof, the lugs 24, which are adapted when in normalposition, to engage the sides of the reversible lifting fire bar 1 toprevent lateral movement thereof. Ijlach of the reversible lifting firebars 1 is adapted to be supported upon two of the rocking bars 21, whichcarry the sleeves 23 which are movable in the slots 25 formed betweenthe converging edges of the, upper and lower sections and upon oppositesides of the depending wings 8, said slots 25 being preferably curvedwhereby it will be understood that the supports for-the bars serve adouble purpose, that is one of-thesupports for each bar acts as a guide,for the bar in its movement, while the other support acts as a pivot forthe bar, de ending .upon the direction of movement the bar. It will benoted that while we have described the slots 25 as if they were twoslots, we desire it understood that in some instances, and as shown,these may be considered as one slot,

, preferably curved to seat the sleeves 23 and I thus form a .proper'bearing between the parts, so that the rocking of the bar in either drection will be roperly accomplished either of the seats orming thesupport or "pivot upon which the lifting fire bar is rocked dependingupon the direction of movement thereof. By roper operation of the bar20, for .examp e, in the direction indicated by the arrow in Fig. 1, oneend of the reversible lifting bar is elevated into the position seen inFig. 5, the slot 25 upon one side permitting this movement and therocking bar 21 on the other side serving as the pivotal supporttherefor,,but when the bar 20 is moved in the opposite direction, theother end of the reversible lifting fire bar is elevated into theposition seen in Fig. 6 and the other rocking bar 21 will serve as thesupport for the opposite end of the lifting fire bar. By this means itwillbe noted that the lifting fire bar can be rocked in either directionas desired with evident results. WVe desire itunderstood that thereversible lifting fire bars can be used in conjunction with the rockchoppers or not as previously stated, if so desired.

In order to remove any one of the lifting fire bars from a grate withoutdisturbing the others, the upper section 2 is disconnected from thelower and can'be removed and the latter is released from engagement withthe bar 20 after which the lower part can be removed.

It will be understood that the lpgs 24 on the sleeves 23 engaging .Withthe sides. of the lifting fire bar revent lateral movement of saidlifting'fire ar.

In some instances we may deem it advisable to connect a series of thesereversible lifting fire bars and for this purpose we'have provi ed anangular opening 26 which is adapted for the reception of an angular bar,which extends across the grate and thus congects a series of thereversible lifting fire ars.

Having thus described our invention, what referably form the two'Letters Patent, is

we claim as new and desire to secure by 66 In a device of the character.described, a hollow lifting fire bar having a plurality of seats, and aplurality of supports for said seats one of said supports serving asaguide 70 for the bar in its movements when the other support serves asthe pivot for the bar.
